20/20SH
Hydrogen Flame Optical Detector
The SharpEye Triple IR (IR3)
Hydrogen Flame Optical
Detector 20/20SH is a selfcontained, triple-spectrum
flame detector specifically
designed for the detection of
hydrogen flames. The optical
sensors and filters have been carefully selected to
ensure the greatest degree of spectral matching to
the radiant energy emitted by the hydrogen fire and
the lowest degree of matching to non-fire stimuli.
The well-known Triple Infrared Spectrum design
incorporated in the various SharpEye Optical Flame
Detectors has been further developed in this
detector to include sensors with special filters with
spectral bands typical to hydrogen flame emission
main combustion product - water vapor (H2O) in
the 1-4 microns band and reference filters to
discriminate background radiation.
This highly advanced detector uses programmable
algorithms, which check the ratio and correlation
of data, received by the three sensors. The
microprocessor design allows for unique field
programmability, making the 20/20SH highly
immune to false alarms.
The detector has applications in a wide range of
industrial and commercial facilities that use hydrogen
fuel cells, hydrogen gas generators and hydroxyfuels. As the hydrogen community moves towards
commercialization, the new emerging use of
hydrogen for automotive transportation requires
special safety measures for the unique refilling
stations, storage tanks and special hydrogen fuel
cells handling facilities.
* Note: The hydrogen flame detector is NOT designed to
detect hydrocarbons fires.
